Take Off My Aviation Era

, The fastest update to take off the latest chapter of my aviation era!

Wind tunnel group!

If I switch to other industries, I guess I really don't understand what that thing is. The problem is that they are all power outlets, and the wind tunnel group in Cotton City is one of the largest electricity consumers in the province.

Even some of you here have undertaken the maintenance and repair work of the wind tunnel group circuit in Cotton City before. They know that it is a top scientific research institution, and it has close ties with the military and other national-level scientific research units. They are also aircraft and rockets. High-end is not something ordinary people can use.

So when I heard that the twenty-third branch could actually use the cotton wind tunnel group, the leaders of these substation companies were a little uncomfortable. How strong the background is to do this, it seems that what drones are in front of me, Hmm~~ Reliable!

If other people were just shocked, then Zhang Ping should be shocked. You must know that he spent nearly two months in the Yonghong factory for the towing model. He also knew a little bit about the inside story of the aircraft development. I heard a designer from the Craft Department of Yonghong Factory say that if you want to solve it completely, you have to use a wind tunnel to simulate the weather characteristics of Linxinghe.

It is a pity that although the Yonghong factory is an aviation factory with more than 10,000 people, it is not easy to approve the wind tunnel group test.

Zhang Ping was very disappointed at the time, but there was nothing he could do. As the so-called interlacing is like a mountain, he didn't even have any tricks.

How could it be that a branch of FATEK has such a strength? Wait~~ I seem to have heard it from somewhere. The 23rd branch seems to be different from the other branches of Yonghong Factory. It seems to be more closely connected with the locality. Well~ It seems that what I said is true!

Lin Guanghua watched the leaders of the substation company whispering in surprise one by one, his back straightened up again, yes, with a long face, he thought that Lao Zhuang’s words were redundant, it seems that the power is spoken. People are still very professional.

So he coughed and pointed the telescopic ruler in his hand to the center wing: "So we finally determined the layout of our TY-1 UAV based on data and after many experiments. The optimized flat wing not only strengthened the structure of the aircraft. Strength, and the optimized airfoil also contributes to the increase of lift, reduces fuel consumption while increasing the space time; at the same time, we combine the tail beam with the wing to form a double vertical tail, which stabilizes the fuselage It can also increase the maneuverability of the aircraft..."

This paragraph is the focus of Lin Guanghua's presupposition, so he is very hard to talk about, and he can't wait to get his thoughts and experience in designing this drone out of his brain, so as to get the approval of the people present.

It’s a pity that the professionalism is too strong, the lift-to-drag ratio for a while, and the Bethlehem formula for a while, not to mention the leaders of the substation company, even the 23rd branch is also collectively dizzy, and in the end it is around Zhang Ping. I took a look at the venue that was about to be hypnotized, and carefully interrupted Lin Guanghua’s energetic introduction: "Um... Engineer Lin, can you first talk about how long the guide rope your aircraft can tow? How many times? Do you know that these two are the most important for our Linxinghe power transmission and transformation project."

"Ah~~"

Lin Guanghua, who was not quite comfortable, was a little disappointed by this question. He hasn't said the most important straight-wing wind tunnel test research behind him. You must know that it is his graduate research topic, the most core thing.

However, disappointment is disappointed. The customer has to meet the request first. This time I didn't say it. I will talk about it next time.

So Lin Guanghua nodded: “Because of the use of the 10-horsepower piston engine developed by West Air and the unique structure of our aircraft, the load capacity of the TY-1 UAV reaches 58 kilograms, which means that it can operate under normal weather conditions. Down, tow the guide rope of one thousand six to two kilometers."

"Lin Gong, are you telling the truth?"

Zhang Ping was immediately excited when he said this. If the plane in front of him really exceeded the towing distance of one kilometer, then it would really solve a big problem for them.

It is necessary to know that the cable crossing the fixed tower on the opposite bank of the Linxing River is close to one kilometer away from the river bank due to the terrain. Therefore, towing the cable to the opposite bank only solves part of the project, and the rest has to rely on the construction workers to use manpower to remove the heavy The cable was pulled a little bit along the mountain road to a fixed tower nearly a kilometer away, and then it was erected.

This process is both time-consuming and labor-intensive, and it also worries the substation company up and down. Unfortunately, this difficulty can only be done backwards before crossing Lin Xinghe. After all, it takes time and effort to complete it, unlike Lin Xinghe even if it is hard to do. indefinite.

Now I heard that the TY-1 UAV can tow more than 1,600 meters, which not only solves the problem of crossing the Linxing River, but also solves the subsequent towing cable.

As a result, the Linxinghe Power Transmission and Transformation Project immediately greatly shortened the construction period, how to keep Zhang Ping from excited.

However, Lin Guanghua suddenly became very embarrassed when he heard that, for some reason, Zhang Ping's heart suddenly sank when he saw it, and he secretly said that it would not be this engineer Lin bragging.

At this moment, Zhuang Jianye, who had not spoken all the time, suddenly said: "That's it, Manager Zhang, our aircraft is fine, but our remote control device has mediocre performance. In theory, it can only be effective within a range of two kilometers. The actual test found that the signal will be weakened if it exceeds 1,500 meters, so..."

Zhuang Jianye didn't say the following words, but smiled apologetically at everyone, the meaning is very simple, more than a kilometer distance, we can't help it.

In fact, the same is true. The 23rd branch can use the wind tunnel to build the aircraft platform, but the remote control device is a little bit blind. There is no way to ask someone to buy a set of imported airplane remote control device to make up the number, even though the aircraft can be made up. Fly, but the real performance can not fly.

It's like a first-class engine with an N-stream gearbox. No matter how powerful it is, it won’t be the same~www.readwn.com~ It's embarrassing to think about it.

Lin Guanghua is generally satisfied with the TY-1 UAV, but he is very concerned about the remote control device. He feels that this is the biggest flaw in the aircraft he designed and developed, so when Zhang Ping asked him, Lin Guanghua was a little hard to tell.

Fortunately, Zhuang Jianye was thick-skinned and made a supplement, which relieved Zhang Pingping, but he was not disappointed. Instead, he asked: "Can it be done within one thousand and two hundred meters?"

"If the visibility allows, no problem!" Zhuang Jianye replied.

"That's good, that's good!" As soon as I heard a thousand or two meters, Zhang Ping smiled again. The distance of the fixed tower was only one kilometer. As long as the fixed tower was able to be here, they would be very satisfied. Thousands of six, two thousand, they are not as good as tasteless.

So he laughed and asked a key question: "How much is your plane?"

"Sixty-five!" Zhuang Jianye was also unambiguous, reporting a crunch.

It's just that the leaders of the opposite substation company listened and took a breath, knowing that at the moment when ten thousand households are scarce, sixty-five thousand is simply a sky-high price.
